Andrew Dunham	48f6c1eba4	control/controlclient: improve handling of concurrent lite map requests Prior to this change, if we were in the middle of a lite map update we'd tear down the entire map session and restart it. With this change, we'll cancel an in-flight lite map request up to 10 times and restart before we tear down the streaming map request. We tear down everything after 10 retries to ensure that a steady stream of calls to sendNewMapRequest doesn't fail to make progress by repeatedly canceling and restarting.

M. J. Fromberger	c09578d060	.github: update tibdex/github-app-token to release v1.8.0 (#7495 ) The main motivation for this change is to stop using the deprecated set-output function which triggers deprecation warnings in the action.

M. J.

Andrew Dunham	be107f92d3	wgengine/magicsock: track per-endpoint changes in ringbuffer This change adds a ringbuffer to each magicsock endpoint that keeps a fixed set of "changes"–debug information about what updates have been made to that endpoint. Additionally, this adds a LocalAPI endpoint and associated "debug peer-status" CLI subcommand to fetch the set of changes for a given IP or hostname.

Brad Fitzpatrick	49e2d3a7bd	words: add word we forgot I explained this tails/scales list to my 5yo and he looked at me like it was the most obvious idea ever. Of course we'd make such lists at work! What else do grown-ups do all day? And then he wouldn't stop talking about coelacanths and I had no clue what he was saying or how to spell it until I asked my phone and the phone apparently understood me and I realized it was a fish and he was helping me? I think? Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	2 years ago

Aaron Klotz	9687f3700d	net/dns: deal with Windows wsl.exe hangs Despite the fact that WSL configuration is still disabled by default, we continue to log the machine's list of WSL distros as a diagnostic measure. Unfortunately I have seen the "wsl.exe -l" command hang indefinitely. This patch adds a (more than reasonable) 10s timeout to ensure that tailscaled does not get stuck while executing this operation. I also modified the Windows implementation of NewOSConfigurator to do the logging asynchronously, since that information is not required in order to continue starting up.

David Crawshaw	387b68fe11	tsnet: generalize loopback listener to include SOCKS5 Some languages do not give you any useful access to the sockets underlying their networking packages. E.g. java.net.http.HttpClient provides no official access to its dialing logic. ...but everyone supports proxies. So add a SOCKS5 proxy on the listener we are already running. (The function being revamped is very new, I only added it in the last week and it wasn't part of any release, so I believe it is fine to redo its function signature.)

Andrew Dunham	df2561f6a2	ipn/ipnlocal: stop netmap expiry timer when resetting control client This prevents a panic where we synthesize a new netmap in setClientStatus after we've shut down and nil'd out the controlclient, since that function expects to be called while connected to control.

Brad Fitzpatrick	0f4359116e	tsnet: add UDP support to Server.Listen No ListenPacket support yet, but Listen with a udp network type fit easier into netstack's model to start. Then added an example of using it to cmd/sniproxy with a little udp :53 handler. No tests in tsnet yet because we don't have support for dialing over UDP in tsnet yet. When that's done, a new test can test both sides. Updates #5871 Updates #1748 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	2 years ago

James Tucker	7b73c9628d	version/distro,wgengine/router: raise WSL eth0 MTU when too low WSL has started to set the eth0 default route interface default to 1280 MTU, which is too low to carry 1280 byte packets from tailscale0 once wrapped in WireGuard. The change down to 1280 is very likely smaller than necessary for almost all users. We can not easily determine the ideal MTU, but if all the preconditions match, we raise the MTU to 1360, which is just enough for Tailscale traffic to work.
